The boys of "South Park" will be back for three more seasons in a new deal inked by Comedy Central.Comedy Central

For nearly two decades, “South Park” has lambasted . . . everything. The cartoon’s raw satire offends left, right and center; all races and religions — and atheists, too. But some are just too dense to get it.

This week’s season premiere slapped “social-justice warriors” — extremists out to police every word for bias.

“PC Principal” takes over the school attended by Kyle, Stan, Kenny and Cartman, the four kids at the show’s heart.

Kyle gets two weeks’ detention for daring to tell a fourth-grader, “I don’t think Caitlyn Jenner is a hero” — which the principal calls “transphobic and bigoted hate speech.”

Later, PC Principal beats Cartman within an inch of his life for not falling into line.

Enter the “warriors.” Culture site Bustle complained the show made it “seem like a bad thing to strive for correct language around transgender issues.”

“Comedian” Peter Coffin spent hours tweeting about the unfairness of it all.

Film critic Bob Chipman whined that creators Matt Stone and Trey Parker have “slowly morphed into the Trump of TV comedy.”
